I can't print from Firefox. I followed instructions in 'Troubleshooting' under 'Reset Firefox printer settings' but print.print_printer is not there. I tried 'Reset all Firefox printer settings' and I can't open 'prefs.js' at all. Help!

Don't try to open the prefs.js file with a double click. That makes Windows try to run the file as a JScript files and that fails.

Did you check the about:config page in Firefox?

When I do about:config, there is no print.print_printer (as it says in the troubleshooter) Also, I can't open prefs.js using any method. I get an error code.
